n 1 Claim. This invention is directed to shoe construction and is primarily concerned with the detailsl of construction of a shoe of the molded outsole type, particularly but not exclusively intended for womens sport wear.

The use in footwear of a molded outsole, thaty is, an outsole formed from a sheet of ordinary sole leather which has an upstanding peripheral iiange, has heretofore been limited generally to shoes of the moccasin type and bedroom slippers. However, there are also instances in which this construction has been used in ordinaryv street shoes, a particular example of this being the patent to Levin andr McGee, No. 2,200,068, of May 7, 1940, which discloses a more or less conventional type of shoe in which the molded outsole extends upwardly and forms a part oi' thefupper.v

As distinguished from shoes of this type, thepresent invention contemplates a construction in which the molded outsole extends only to a point -approximating the sole line of the foot thereby creating the appearance of' what isknown in the trade as a platform sole. Y

A platform sole as used in both mens and` womens shoes comprises, generally, a plurality of layers of leather and filler superimposed one over the other and intended to provide a very strong and sturdy sole and at the same time to impart to the shoe a somewhat unique and attractive appearance.

The shoe of the present Yinvention resembles a shoe having a platform sole in that the upper commences. at a point which is relatively high up on the shoe due to the extra thickness of the sole. However, instead of being formed entirely from a plurality of layers as in aplatform sole, the sole contemplated by the present invention is formed from a single piece of molded sole leather having an upstanding flange around the. periphery. The interior of this cup-shaped sole is then built up to a level approximately; equal to the upper edge of the flange An upper is then secured to the upper edge of the ange by stitching, lacing or the like.

Another feature of the present invention has been the general adaptation of the molded outsole type of construction to shoes intended for ordinary street wear. To this end the present construction contemplates the lasting of the upper to an insole sheet adapted to reenforce and strengthen the outsole and the provision of separate heel elements which may be interior of or exterior of the molded outsole.

With these general concepts in mind, one of the objects of the invention has been to provide a shoe which resembles i-n appearance ashoe having a platform sole but-'which utilizes 'a' molded outsole having anupstanding flange `terminating approximately at the sole line of the foot.

Another object of the invention has been the provision of a two part insolev construction com" prising a flexible sheet member adapted: to re*- enforce andv strengthen theoutsole and a cushioning filler member adapted tol be superimposed over the sheet member. y Y

Another object has been the provision of' a separate heel member which maybe positioned interior of the molded outsole.

Another object has been the adaptation of `ordinary shoe Aconstruction to a shoe ofl the molded outsole type to provide a shoewhich is of unusual and attractive appearance and one which has wearing qualities equal or superior to those of shoes of more conventional construction.

Other and further objects and-advantages will be apparent from a consideration of the furtherV and more detailed description of' the invention when considered in conjunction with the drawing in which:

Figure l is a side elevation of the-exterior of a shoe of the type of the invention.

Figure 2 is a longitudinal section through the middle of the shoe illustrated in Figure 1. -l

Figure 3 is a perspective viewfof'the same shoe particularly illustrating the details of' the heel assembly.

Figure 4 is a longitudinali section throughV a shoe illustrating a slightly modied form of the invention.r i

In Figure l a shoe is indicated generally at i. This shoe includes aV molded' outsole 2 which has its` upper edge terminating at 3, a'point which coincides approximately with'the'sole line of the foot. The upper is indicated' generally at 4 and may be securedto the molded outsole 'along' the upper extremity of the flange by stitching or lacing as illustrated.

The details of the construction of the shoe are A membervlissuperimposed on the sheetV and may or may not be secured to it. A conventional i sock lining I'I is superimposed on the filler member. In theheel construction a separate heel meinber I2 which may be wood is positioned in a preformed heel depression in the molded outsole and has a narrow projection I8 extending forwardly over the instep portion of the shoe. This projection provides asubstantially level surface on the interior of Vthe/shoe and helps to prevent sagging ofthe instep of the foot. The entire wood heelV is held in place by the insole sheet 6 which completely covers it. .The top lift maybe secured to the heel through the molded outsole Vby nails suchas I3. j Y 1 Y In the modedconstruction shown in Figure ward element Iris formed from felt and isintended to be more resilient than the rear element v Y Vwhich maybe paperboard or the like. This type Y of construction tends to increase the springiness of the forward part of the shoe although, if desired, the entire member may be `formed from felt or some other resilient material. s Y

In the formV of the invention shown in Figure 4l,`

the shank iron is of conventional construction and Amay be placedin position after the heel element I 2' and the filler I 6 have beenVV positioned and secured on the interior of the-molded outsole. In this figureY the resilientv filler elementV has been omitted.

It has been found that the provision of a strong resilient insole member and the securing of` this 4 a shank iron I4 is utilized-in lieu of the forward projecting portion of the heel member I8 shown inY Figure 2. This iron has an end restingon thev heel 2IlV and extends-forwardly over'the instep portion of the shoe.r The shank iron may b e held Y in-,position by the cover I5 which may be of leather andwhich may be adhesively secured to the heel and the molded outsole. The insole sheet 6 which has been vpreviously assembled with the upper f on a last may then be adhesively secured to the shank iron cover and' outsole. 'Ihe vcavity formed beneath the shank iron may be filled with any conventional filler I6 which may be cork or leather dust. Y

Y vIn' theY construction oiv the shoe generally a molded outsole is first formed by saturatingV a Y blank of sole leather and then molding this blank around Va last of the desired contours.V This opn eration may be performed mechanically or by,V hand, or by a'combination of both methods. After the leatherchas/driedand hardened the'upper edge is trimmed Vto provide a ange .of substan-V tially uniform height around the periphery of the sole. 'I'his height may be increased somewhat at the heel portion'and, in the formillustrated in Figures 1 and-2, it is desirable that a depression be 'formed'at the rear for the reception of the heel member I2 interiorrof the molded outsole;

'I'heredges of the ange should be skived as shown to provide an improved appearance.

The upper is then lasted to an insole in the conventional way. The margins of the upper may be folded over the lower surface of the insole r'sheet 6 as illustratedand adhesively secured thereto.

'Iherinsole sheet may be formed from cloth, leather or compositions and preferably should be of sub-` v55. at the'rear thereof for the reception ofanin- Y Finally, the cushioning insole'l'lller 'I-S may beY placed in position and secured thereby adhesive or simply held in the form of filler illustrated in Figure 2, the forposition by friction; In

member to the interior of the outsole greatly strengthensV this type of construction. The provision of theresilient filler member of substantial thickness is likewise an important feature of the invention as its use builds up the interior of the shoe to the level of the flange of the out'- sole so that the upper part of the foot is covered only by the Yupper of the shoe and the comforty of the construction isY thereby greatly increased.; Although the filler member is of generally resilienth7 material such as the felt and paperboard Vpreviously-mentioned, it has been found thatf theserand other resilient materials have sufficient body to support the upstanding flange of the out-..

sole and maintain it in substantially vertical positionwith respect to the body of the outsole. Y

Were it not for this support 'theiiange would tend to incline inwardly because of the pull. exerted by the upper. Such an inclination wouldv tend to destroy the appearance of the shoe byv creating the impression that the fiange was al part of the upper rather than the edge'of the sole. There is also a rstructural disadvantage in permitting the flange to flex back and forthas this flexing tends rto weakenithemolded outsole along the line where the flange joins the base of the outsole. Unless'the flange isY maintained insubstantially rigid position any continuing flexing of this sort may tend to weaken the outsoleY to a point where moisture andwater can enter.^ The construction offers opportunities Vfor attractive styling in the contrasting of the material of the upper With the flange of the outsole.

Having described my inventionyI claim: A'shoe comprising an outsole molded from sole I leather and having' an upstanding peripheral flange, said outsole being configurated to provide an arch support portion and having a depression dependent heel element, a rigid heel element positioned in said depression, an arch supporting member extending forwardly from the heel element across the arch support portion of the out'-n sole, an insole positionedr on the-*heel element and outsoie, said insole including a resnient nnerA of' substantial thickness contacting and supportingthe outsole flange against Vinward flexing and having its upper surface-substantially 4coinciding with the upper edge of the outsole flangeand an upper secured to said flange; said upper holding said outsole flange against outward flexing. f JOHN HENRY SCHROEDER,HK
